The present invention relates to a releasable anchor for securing a boat or marine vessel to a desired position having a weighted body with a central bore extending throughout its length through which an elastic strip is pulled in such a way as to form a closed eye on one end of the weighted body and with the remainder of the elastic strip being frictionally held within the central bore of the weighted body. The elastic eye along with the weighted body may be attached to one end of an anchor line and when the anchor becomes bound by an underwater obstruction a boater may exert tension to the elastic eye by applying a pulling force to the anchor line. The exerted tension will cause the elastic strip to stretch thus reducing its diameter inside the central bore of the weighted body until the friction will no longer withhold its exit from the central bore of the weighted body. This action allows the anchor to release from the anchor line at the point of connection.
